Thats a good idea , certain to be timesaver , and looks realy neat. To be honest with You it looks to neat , even by german standards.
Mine are going to be more rough if you know what i mean.
I tried masking both sides of the weld with tamiya tape , leaving 1/3 mm gap between which i fill with filler. Then before it dries out i rough it up with the blade , creating weld like line. If its done in short sections at the time , can create good weld effect. After it dries delicate sanding with 1500 grade sandpaper , primer , and its ready. Im gonna go this root.
